Relationships between voltage and angle stability of power systems

  title={Relationships between voltage and angle stability of power systems},
  author={Costas D. Vournas and Peter W. Sauer and M. A. Pai},
  journal={International Journal of Electrical Power \& Energy Systems},
This paper discusses modelling and theoretical issues associated with voltage and angle stability of power systems. A time-scale decomposition is performed to illustrate how the critical modes can be identified with reduced-order models and the bifurcation phenomena can be explained with these low order models. Examples are given for single and multi-machine systems.
